Sensors turn a field into data.
Robots cannot act on a field they cannot measure. The modern agro robot carries a stack of sensors that describe position, plant health, soil state, and weather in near real time.
Imaging sensors
RGB cameras capture color and shape. Multispectral and hyperspectral cameras extend vision into infrared bands to detect plant stress before it is visible to the human eye.
Depth and ranging
LiDAR and stereo cameras build 3D point clouds of crops, rows, and obstacles. They are essential for navigation and selective picking.
Soil and environment
Soil moisture probes, pH sensors, nitrate sensors, and weather stations inform irrigation, fertilization, and spraying decisions.
Positioning
GNSS with real-time kinematic corrections provides centimeter-level positions outdoors. IMUs and visual odometry fill gaps in GNSS-denied areas such as greenhouses and orchards.
